Abstract
The utility model discloses an omnidirectional pressure resistance testing device of liquid flexible packaging product, wherein the utility model comprises a sealing device, the sealing device is formed a sealing space; the sealing device is connected with an air extraction pipeline leading to the sealing space; the air extraction pipeline is connected with a vacuumized device; and a pressure display device is arranged between the air extraction pipelines connecting the sealing space and the vacuumized device. The utility model can provide omnidirectional pressure to be acted on the packaging in the sealing space, can detect the most weak part of bearing the pressure, has accurate testing data, simple structure and strong practicability, and is simple and convenient in operation.
Description
Technical field
The utility model relates to a kind of pressure test device, is a kind of omnidirectional's pressure resistant testing device that is applicable to the ability to bear of liquid its packer pressure of flexible packing products of test specifically.
Background technology
Flexible packing material is good, in light weight with the barrier property to light, oxygen and moisture that it has, transportation stores characteristics such as convenience, exquisite appearance, has become one of principal mode of liquid packing.The liquid flexible packing product is because of the needs of its packages for liquid thing and productions such as storage, carrying, logistics requirement, and the flexible packing products resistance to pressure behind its filling and sealing is one of important performance of product.
Traditional detection method is that the upper and lower both direction at the liquid flexible packing product applies certain pressure, with detect its break or seepage before the maximum pressure value that can bear.The shortcoming of this mode is only upper and lower both direction to be exerted pressure, not necessarily can detect the weak part that it bears pressure, and, also might strengthen the local ability of bearing pressure to the method for testing that upper and lower test board face is exerted pressure, cause the test data distortion.
Summary of the invention
At the deficiency that prior art exists, technical problem to be solved in the utility model is, provide a kind of simple in structure, with low cost, data are accurate, the liquid flexible packing product omnidirectional pressure resistant testing device of force value that can full test liquid flexible packing product.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of liquid flexible packing product omnidirectional pressure resistant testing device, comprise a packoff, described packoff forms a seal cavity, on packoff, be connected with an exhaust pipe that leads to seal cavity, connect vacuum extractor on the described exhaust pipe, between the exhaust pipe that connects seal cavity and vacuum extractor, pressure-display device is set.
Above-mentioned liquid flexible packing product omnidirectional pressure resistant testing device, described packoff is formed by base and with the transparent sealed cover that base is sealed and matched.
Above-mentioned liquid flexible packing product omnidirectional pressure resistant testing device, described vacuum means are changed to aspiration pump or manual pump bowl.
The advantage of the utility model liquid flexible packing product omnidirectional pressure resistant testing device is: can provide omnibearing pressure in seal cavity, act on this packing, can detect it and bear the weakest position of pressure, test data is accurate, and this apparatus structure is simple, easy and simple to handle, practical.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and the specific embodiments the utility model is described in further details;
As shown in Figure 1, a kind of liquid flexible packing product omnidirectional pressure resistant testing device, comprise a packoff 1, the sealing device forms a seal cavity 11, in seal cavity 11, place packing 5 to be measured, on packoff 1, be connected with an exhaust pipe 2 that leads to seal cavity 11, the other end at exhaust pipe 2 connects vacuum extractor 3, between the exhaust pipe 2 that connects seal cavity 11 and vacuum extractor 3, pressure-display device 4 is set, this pressure-display device 4 can be the display that pressure transducer connects, also can be other gaseous tension proving installations such as tensimeter, because of it is a prior art, so seldom explain, packoff 1 is formed by base 12 and with the transparent sealed cover 13 that base 12 is sealed and matched, this transparent glass cover 13 can be made with glass, also can make with transparent plastic; Vacuum extractor 3 can be aspiration pump or manual pump bowl.
The liquid flexible packing product seals after the can under atmospheric pressure environment, and promptly package interior has the absolute value pressure of 0.1MPa.Liquid flexible packing product to be measured is placed in the sealed space, this space is vacuumized.Pressure in the sealing space begins to descend, place the pressure of original 0.1MPa in the liquid flexible packing product in the seal cavity, greater than the pressure in outside seal space, the difference of its pressure promptly is the pressure that acts on the liquid flexible packing product, and this pressure is omnibearing.With the pressure of vacuum extractor reduction seal cavity 11,, measure seal cavity 11 vacuum tightnesss that the liquid flexible packing product breaks or seepage is preceding and can converse the maximum pressure value that the liquid flexible packing product can bear with the force value of sensor seal cavity.
Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of making, remodeling, interpolation or replacement all should belong to protection domain of the present utility model.
